The role of HVDC in the electrical development of Canada

The development of high-voltage converting equipment has spurred interest within the last decade in the technical and economic aspects of HVDC (high-voltage d-c) transmission. This article examines the economics of power transmission and those areas of electrical development in Canada where transmission by HVDC is a possible economic choice. The discussion requires some rather general groupings of load areas and hydraulic resources in which existing utility and provincial boundaries are to some extent ignored and the resources treated as national or even continental assets
